HARRY BULTMAN, OF OSGOOD, INDIANA.

- LAND-ROLLER.

Specification of Letters Patent.

Application filed February 21, 1916. Serial No. 79,650.

' citizen of the United States, residing at Osgood, inthe county of Ripley, State of Indiana, have invented a, new and useful Land-Roller; and I do hereby declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to land rollers, and an object of the invention is to provide an apparatus of this nature, which is simple, efficient and practical in construction, and inexpensive to manufacture.

Another object of the invention is to provide a land roller, which will so flex, that the rollers will accommodate themselves to the unevennesses and the irregularities in the soil, particularly without .unbalancing the operators seat toward one side or the other.

Another object of the invention is to construct the frame in two sections (each of which carries a roller), so that the inner end of one or the other of said sections will raise or lower slidably, in order that said rollers will more efliciently accommodate themselves to the unevennesses and irregularities of the soil.

Another object of the invention is to provide yieldable means consisting of yieldable blades extending transversely and connecting the sections of the frame, to yieldably support the tongue of the apparatus, on which tongue the operators seat is supported, whereby the rear or the forward parts of the sections of the frame will tilt up and down. -The connections of said blades or yieldable means to the sections of the frame are pivotal, and each connection is disposed centrally on each section, so that the inner or outer end of each section of the frame will move up or down, whereby the inner or outer ends of the rollers will accommodate themselves to the irregularities of the soil.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure l is a plan view of the improved land roller constructed in accordance with the invention. Fig. 2 is a s1de view of the land roller, showing one section tilted at a different angle to its ad- ]acent section. Fig. 3 is a rear view'of the land roller, showing the outer ends of the sections of the frame tilted downwardly more than the adjacent or inner ends. 'Fig. l is a rear view of the land roller, showing the inner ends of the sections of the frame lowered more than the outer ends of the sections thereof.

Referring more especially to the drawings, 1 and 2 designate the two sections of the frame of the land roller. These sections are rectangular in plan view as shown, and the inner end of the section 2 is provided with eyes 3, which are engaged by the vertical elongated loops 4 upon the inner ends of the section 1, so that, as will be seen in Fig. 2, the rear part of the section 2 may be tilted downwardly, whereas the rear part of the section 1 may be tilted upwardly. The usual land rollers 6 and 7 have their pintles 8 journaled in bearings of the inner and outer ends of the sections of said frame. Extending upwardly to the rear and forward bars of each section substantially centrally between the ends of said bars are bolts 9 and 10 having laterally extending cylindrical portions 11 terminating in heads 12. Fixed to the cylindrical part 11 of the rear bolt 9 is a roll 13 of a spring blade 14:, the roll 15 at the opposite end of which is pivotally fixed to the lateral cylindrical portion 11 of the rear bolt 10. Pivotally-connected to the cylindrical part 11 of the forward bolt 9 by means of a roll or sleeve 18 is one end of the forward spring blade 16, the roll or sleeve of the opposite end of which designated by the numeral 9 is sleeved pivotally on the cylindrical part 11 of the forward bolt 10. By this construction and arrangement of the spring blade, the sections of the frame are so universally and.

yieldably connected, as to permit the sections of the frame to yield universally with relation to each other, in other words, whereby either the inner or outer ends of either land roller or both thereof may raise and lower and accommodate themselves to the unevennesses or irregularities of the soil. A tongue 20 (which is provided with an operators seat 21 and a foot rest 22) isbolted to the spring blades by means of the bolts 23. By mounting the tongue in this manner, it will be seen that the lowering or Patented June 13, 1916.

raising of either end of either of the rollers,

laterally, forwardly or rearwardly, to the extent of being perceptible, or to the extent of rendering it uncomfortable for the operator.

The invention having been set forth, what is claimed as new and useful is 1. A land roller comprising a frame consisting of two sections arranged side to side, land rollers journaled transversely in said sections, the adjacent sides of said sections having connections, whereby either the for ward or rear parts of each section may raise and lower on the land rollers, a pair of spring blades, the'ends of each blade being pivotally connected between the ends of the sections, and a tongue supported on said blades and provided with an operators seat.

2. A land roller comprising a frame consisting of two sectlons arranged s de to side,

land rollers jou'rnaled transversely in said will not unbalance the operators seat either 7 sections, the adjacent sides of said sections having connections, whereby either the forward or rear parts of each section may raise and lower on the land rollers, a pair of spring blades, one arranged forwardly and one 'rearwardly, both extending transversely, the opposite ends of each blade having pivotal connections with substantially central portions of each section, the pivotal connections of the forward blade being axially alinedwith the pivotal connection of the rear blade, and a tongue including an operators seat supported upon the blades.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
